Dear Prudence,
I dated a man who was separated from his wife (they were both aware of the separation, thankfully). While we were dating, he stayed the night a handful of times. The last time, I noticed that a pearl necklace my father had given me was missing. I turned the house upside down, but never found the necklace. Eventually our relationship fizzled and he reconciled with his wife. Then, a mutual friend forwarded an image his wife sent out of a beautiful pearl necklace he had given her to symbolize their new commitment to each other. This necklace already has sentimental value—to me! The necklace has unique elements, and I have photos of myself wearing it. When I tried to ask the guy about the necklace, he blocked my number. I could contact his wife. I don't want to squash their reconciliation, but I can't think of any delicate way to explain the situation and ask for the necklace to be returned. Should I let the necklace go and wish them the best, or should I let her know that her husband is part of the Bling Ring?
